Step 1Let's solve this step by step:
Step 2: Determine the Lewis structure of CO^3²⁻
- Carbon (C) is the central atom - Oxygen atoms are bonded to carbon - Total valence electrons: 4 (C) + (3 × 6) (O) + 2 (charge) = 24 electrons - The structure involves resonance with three equivalent oxygen structures
Final Answer
D. eg = trigonal planar, mg = trigonal planar
